extensive nodule collection in the Pacific (7–15°N) on the west coast of North America. However, it was Mero4 who described the economic potential of manganese nodules, and predicted that mining would start in 20 years time. This caught the world's attention into developing polymetallic nodules as a resource for metals in the future.

RareEarth Minerals Hold Promise for Seabed Mining

An Overview of Seabed Mining Including the Current State

Nodules are potatolike in shape, 4–10 cm in diameter, and are thought to form in a process that takes millions of years in which manganese in seawater adsorbs to a nodule substance that is oxidized by bacteria and becomes nodule matrix (Blöthe et al., 2015 Vanreusel et al., 2016).

Feasibility Study on Manganese Nodules Recovery in the

Manganese Nodule Recovery and aims to target an outreach to the general public in terms of awareness on the potential of Seabed Exploitation. This book has been very instrumental in developing a thought process towards the risks associated with the nodule recovery process. These topics have thus suitably been addressed.

Deep sea mining Wikipedia

Deep sea mining is a relatively new [when?] mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean's surface. [1]

How it all began Ecological Aspects of DeepSea Mining

Beside the manganese nodule areas in the CCZ areas with massive sulphide resources at the Mid Atlantic Ridge, in the Indian Ocean and the Pacific are of major interest. Since 2006 Germany has two manganese nodule claims in the CCZ which are explored by the BGR.

Aspects of the statistical analysis of marine ore deposits

The quality of navigation, sampling, mining technology and the profitability of the project strongly influence such analyses. The studies presented here, have two main objectives, namely, to estimate the reserves of manganese nodules and to determine in what order the explored areas should be mined. Several geostatistical methods were used.

The exploration of cobalt crusts is also fundamentally different from the manganese nodule situation in some technical aspects. Manganese nodules can be brought quickly and easily on board with a box corer, similar to a backhoe, and then sampled to measure the metal content, for example.
